Summary

Guardian language-system passes the id GET parameter directly into a PHP exec() call in subtitles.php (line 19) without sanitization: exec(\"php jobs/subtitle_rendering.php \".$login_session.\" \".$_GET['id'].\" ...\"). No authentication is required. An unauthenticated remote attacker can append shell metacharacters to the id parameter to execute arbitrary OS commands on the server.
